Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544688, here are decompositions:
- 31 + 31544657 = 31544688
- 101 + 31544587 = 31544688
- 127 + 31544561 = 31544688
- 137 + 31544551 = 31544688
- 157 + 31544531 = 31544688
- 179 + 31544509 = 31544688
- 271 + 31544417 = 31544688
- 317 + 31544371 = 31544688
Showing the first eight; more decompositions exist.
